Phi Function

[douganc]

Hello,
Can anyone tell me where I am going wrong in this Program?

It's purpose is to display the value of Phi to 50 Decimal Places
When "phi()" is typed on the home screen.

Here is the program:

#cas
phi():=BEGIN
//
LOCAL x;
x:=(1.61803398874989484820458683436563811772030917980576);
RETURN(x);
//
END;
#end

Output: See attached Screenshot.

Thanks !
Colm

hi,
first detach BEGIN after the :=

Code:


#cas
phi():=
BEGIN
//
LOCAL x;
x:=(1.61803398874989484820458683436563811772030917980576);
RETURN(x);
//
END;
#end

after this you won't have that error, but
1.61803398875.
then the rest...

For "all dec" output see here.

The term "phi function" is already occupied

https://en.wikipedia.org/wiki/Euler%27s_...t_function

You could amend to "phi constant"?

[douganc]

Yes of course, it's a constant not a function.
